LONDON, Mar 8:
Effective activities could be used to train the brain to prevent future disorders such as dyslexia, scientists say.
Over the years, several studies have shown that the the brain is able to naturally adjust the frequency of its waves with the oscillations or the rhythm of what it listens at each moment.
However, little was known so far of the consequences of the effect of brain synchronisation, also known as brain-entrainment, in brain regions directly related to language processing.
Researchers at Basque Center on Cognition, Brain and Language (BCBL) in Spain studied this aspect and has thoroughly analysed the brain synchronisation of 72 individuals.
According to Nicola Molinaro, a researcher at the BCBL, the experiment has shown that the synchronisation with speech is more intense when the brain listens to low frequency waves – those related to the accent, tones and intonation of speech.
The study showed that this synchronisation results in a direct activation of the brain regions related to language processing, as is the case of the Broca area, a section located in the frontal lobe of the left hemisphere and involved in the production of the same. In previous work, researchers found that children with dyslexia show a weak synchronisation with low frequency bands, and therefore, a poor activation of the regions related to language processing.
Molinaro said that therapeutic interventions focused on language learning can be developed during childhood by stimulating low frequency auditory components and thus obtain a clearer idea of the sounds that make up the language. (PTI)
